Abstract
Described herein is an extravasation tester that pinches an infusion line closed between a wheel and a platen, and then peristaltically withdraws fluid into the infusion line as the wheel is rolled away from a puncture site. Extravasation is determined to have occurred if little or no blood appears in a sight chamber positioned near the puncture site when a test fluid is withdrawn into the infusion line from the puncture site.
